The Jaguar XKSS is probably the most sought after Jaguar ever built. There were just 16 ever made, 12 of which still exist. Steve McQueen bought his for $5,000 way back when, and it's estimated to be worth $30 million now. And on tonight's Car Matchmaker, we get to see how they keep it running.

This particular XKSS is now kept in the Petersen Museum, and Spike Feresten and Jaguar nut Adam get a chance to see it up close and personal, something that not many people ever get to do.

Instead of letting it sit and rot, the Petersen gives it a workout on their own grounds. But the Petersen doesn't have a track you say. No it doesn't.

But it does have a parking lot on the roof, which is where they take it to keep everything running smoothly. No, they don't take it on the roads, but this is more movement then you'll probably ever see out of an XKSS.
